Students with ADHD sometimes struggle with reading. I have found some tools that improve their reading comprehension and fluency. Audio books and reading software - Recorded books allow students to listen to text, and they are available in a variety of formats. Special playbook units allow users to search and bookmark pages and chapters.
Natural Reader
Optical character recognition (OCR) allows a student to scan printed material into a computer or handheld unit. Then the scanned text is read aloud by a speech synthesis/screen reading system. OCR units are available in stand-alone units, as software, and as portable, pocket-sized devices that display words on an easy-to-read screen. Scanning pens are a big help and are perfect for library research and other reading that doesn't involve a computer.
